Weather News: UK and USA (23.07-29.07)

Weather forecast for the UK stays largely warm and often dry this week. Monday will be hotter still across England, where light winds and long sunny periods will allow temperatures to climb into the low +30 °C across central and southern areas. Meanwhile, much of Scotland and Northern Ireland will continue to see a persistent lingering front bring cloudier weather, with some patchy rain continuing at times. On Tuesday, heat will persist across central and eastern England, while a fragmented band of cloud, rain and showers slides slowly south-east towards Wales and south-west England.

Wednesday will be dry and fine for much of the country, with the hot weather continuing for England. During the latter half of the week, it looks like more widespread heat and humidity will build across England and Wales, perhaps giving the hottest spell of the year so far, while passing fronts will give cloudier and cooler weather for Scotland and Northern Ireland at times.

In the west showery spells of rain develop and push eastwards but fade away to leave a lot of fine weather on Saturday and Sunday. Temperatures probably generally lower than in recent days but it remains warm or very warm in the south.

Weekly weather for the USA

Heavy rain could cause more flash flooding in the East this week as a pipeline of tropical moisture continues to pump over the region.

The instigator for this soaking weather pattern is a powerful plunge of the jet stream – by July standards – which has carved into the East and will sit in place for the next several days. This will be later reinforced by another plunge of the jet stream late this week, blocked by high pressure over the northern Atlantic Ocean.

This pattern is tapping a plume of deep, tropical moisture from the Gulf of Mexico and the Caribbean Sea into the Eastern Seaboard around high pressure in the Atlantic.
